PRC 260cc Heads
Yeah. I need some sort of results through. I really want to see specific results ie 1/8 or 1/4 times ie going from LS3 heads to the PRC heads.
Not really interested in dyno numbers even, but et and mph gained.
I'm sure they are beautiful, but I really want to push these things to the bleeding edge, and I'm not seeing the data as quickly as I would like.

Texas speed claims 40hp over factory heads
Good luck
I'm going solid roller/double fogger/tunnel ram. Looking to spin 8500ish.
Maybe the Black Labels would be a safer bet?
Those mast heads though
badass mother ******* is what they are. Dont forget with bronze guides you will need to use roller rockers in most cases. A good set like jesel or crower will set you back 800+ Trending Topics

Thats why i said custom. rhs offers a porters casting of the ls7 which a few people have programs for. this for a certain class?
Btw..i would look into something a little more custom since your wanting to spin 8500 with a solid roller and 2 foggers..a little more tailored to your application.

LS7 heads won't work on this application.
I am at a 4.030 bore currently. I have a 6.0 iron block, I've heard people of taking these things up to 4.065+ bore before, but I suspect the amount of nitrous I will be using, I will need as much meat in the cylinder walls to handle the pressure.

If I don't go with these 260cc heads, I'll find a set of MAST LS3 heads.

What jet sizes??
An application like this and 2 foggers along with a tunnelr am and solid roller...an off the shelf set wont be enough unless you get extra work on then...exhaust throat and cross section..valve jobs etc will need to be worked on.

I'd be happy to put together a combo for you. I have a spring combo in mind that I think will meet your power & rpm goals. I always like LS7 heads, and even have a ls7 for 4.065" bore. That being said if your bore limited the LS3 260cc head would be a good option. The valves are relocated & the valve angles are altered as well.
